Explanation of Solution

Simulation:

  • Simulation refers to the method of developing a mathematical or logical model for a complex system and examining with the model to find out the result.
  • There are two different types of simulation as follows:
    • Discrete event simulation:
      • It refers to a model in which the changes occur at a discrete point of time and mark those changes of the system at finite interval of time.
      • It is an activity-based simulation and the time is split into small time parts, and then the changes are marked in each part.
      • Discrete event models are represented by using entities, attributes, and events.
        • Entities are used to represent the objects in the system.
        • Attributes are used to represent the features of the system in the object.
        • Events are used to represent the interaction between the objects in the system.
    • Continuous simulation:
      • It refers to a model in which the changes of the system will be continuous and the response over time is defined using a set of differential equations.
      • The characteristics or features of the system will be represented mathematically.

Weather forecasting:

  • Weather forecasting is an example for continuous simulation.
  • Weather forecasting is the simulation used to find the state of the atmosphere.
  • Temperature, wind, precipitation, and cloud are the main characteristics of weather.
  • The interface of the components is modeled using a set of differential equations, which measure the rate of changes in weather.
  • Since, there is a continuous change in the weather and changes are updated periodically, weather forecasting belongs to continuous simulation.
